This work provides guidelines for the practical implementation of security architecture in a particular corporate cloud. The authors are mathematicians and specialists in data modeling and security. Experience of scientific collaboration with industry inspired the authors to attempt to conceptualize the common processes and strategies in cloud security, in order to make security system deployment as simple and transparent as possible. The deployment is broken into several essential steps that allow the functionality of security architecture for any cloud to be split into a set of modules. The continuous verification of security support on all levels (data, processes and communication channels) helps to avoid common security breaches and protect against the most dangerous attacks. Additionally, performing the proposed optimization of the selected set of mechanisms will enhance the efficiency of the security system.

In late 2008, under the long shadow cast by the most severe economic crisis in generations, a revolutionary new form of currency was quietly being shaped. At the time no one could have predicted that an obscure form of electronic money would in less than a decade prove to be the most important financial innovation of the 21st century-a tool that would spark an entire new economic institution: crypto economy. That once-obscure money was known as Bitcoin, and today it is the highest valued digital coin. And though consumers continue to scramble to cash in on the trending currency, the technology behind Bitcoin known as Blockchain, which allows the currency to bought and sold without regulation by a government, remains a mystery to the public. In Crypto Economy, Aries Wanlin Wang provides the definitive blueprint for understanding how Bitcoin, Blockchain, and other digital technologies are disrupting traditional financial institutions and forever changing the world of commerce.

Secure Computer and Network Systems

Modeling, Analysis and Design

Nong Ye, Arizona State University, USA

Computer and network systems have given us unlimited opportunities of reducing cost, improving efficiency, and increasing revenues, as demonstrated by an increasing number of computer and network applications. Yet, our dependence on computer and network systems has also exposed us to new risks, which threaten the security of, and present new challenges for protecting our assets and information on computer and network systems. The reliability of computer and network systems ultimately depends on security and quality of service (QoS) performance.

This book presents quantitative modeling and analysis techniques to address these numerous challenges in cyber attack prevention and detection for security and QoS, including:

the latest research on computer and network behavior under attack and normal use conditions;

new design principles and algorithms, which can be used by engineers and practitioners to build secure computer and network systems, enhance security practice and move to providing QoS assurance on the Internet;

mathematical and statistical methods for achieving the accuracy and timeliness of cyber attack detection with the lowest computational overhead;

guidance on managing admission control, scheduling, reservation and service of computer and network jobs to assure the service stability and end-to-end delay of those jobs even under Denial of Service attacks or abrupt demands.

"Secure Computer and Network Systems: Modeling, Analysis and Design" is an up-to-date resource for practising engineers and researchers involved in security, reliabilityand quality management of computer and network systems. It is also a must-read for postgraduate students developing advanced technologies for improving computer network dependability.
